Counter plan — how to beat Sion

  • Build percentage damage — flat penetration falls off against the stats it stacks

  • Avoid extended fights — its sustain grows with every trade it survives

  • Punish the cooldown — Sion is exposed while its rotation is down

  • Ward the flank — vision is what turns its best opening into a worse one

  • Respect the spike — Riot rates the kit 5/10, so a practised player gets more out of it than the average

Ability details

  • P

Sion balance history

Riot's notes from patch 25.S1.1 to 26.20 change Sion in 4 patches. The latest is patch 26.13, published 2026-06-23.

  1. Patch 26.132026-06-23

    QDecimating Smash

    • Min Damage40 / 60 / 80 / 100 / 120to30 / 45 / 60 / 75 / 90

    WSoul Furnace

    • Mana65 / 70 / 75 / 80 / 85to75 / 80 / 85 / 90 / 95
    Why, in Riot's words

    Sion has been resilient in both solo queue and pro play for a long time, so we're weakening some of his reliable early lane power and resource access without decimating his core tank fantasy.

  2. Patch 25.232025-11-18

    QDecimating Smash

    • Monster Mod150%to165%
    Why, in Riot's words

    Sion is pretty playable in the jungle but is slightly weak and deserving of a small nudge for players who want to yell “COWARDS!” as they barrel up and down the river. We're just delivering a light touch to see how many players want to try their hand at Si-ungle.

  3. Patch 25.162025-08-12

    PGlory in Death

    • Health Lost per Tick2.3 - 24.4 (based on level)to2 - 19 (based on level)

    ERoar of the Slayer

    • Armor Reduction20%to25%

    RUnstoppable Onslaught

    • Bonus AD Ratio (Based on Travel Time)40 - 80%to60 - 120%
    Why, in Riot's words

    AD Sion hasn’t been in a good spot as of late, so we’re here to help him out. We’re starting by reverting Sion's passive tickrate back to what it was before we nerfed it, giving him more time to beat people to death with his fists, and allowing his damage to be more potent when he snipes someone with an E. Finally, we also want the train's impact to be all the more explosive by increasing his bonus AD Ratio on his R. While we know these changes may be broadly power positive, we targeted areas that make AD Sion happier in particular.

  4. Patch 25.042025-02-19

    Base Stats

    • Base Armor32to36
    • Health Regeneration7.5to9
    Why, in Riot's words

    Sion's not in the best state at the moment, and since we're about to nerf a bunch of his main items we're setting him up with some proactive compensation buffs. We're doing this by giving him some base defensive power that he lost from his items. Additionally, Sion currently struggles in lane with a lot of losing matchups, so we're targeting his base armor instead of armor scaling to specifically help him in the early game.

Riot's tips for Sion

Playing Sion

  • You only have very slight turning ability during Unstoppable Onslaught, so make sure to use it in straight paths.
  • Roar of the Slayer is a great setup ability to land a very powerful Decimating Smash.
  • The Soul Furnace buff displays how much shield strength is remaining, use this information to time its explosion perfectly.

Playing against Sion

  • Even if Sion still hits a Decimating Smash, making him release the charge earlier reduces its impact.
  • Use the time after Sion has died to reposition and prepare for his return.

Sion's story

A war hero from a bygone era, Sion was revered in Noxus for choking the life out of a Demacian king with his bare hands—but, denied oblivion, he was resurrected to serve his empire even in death. His indiscriminate slaughter claimed all who stood in his way, regardless of allegiance, proving he no longer retained his former humanity. Even so, with crude armor bolted onto rotten flesh, Sion continues to charge into battle with reckless abandon, struggling to remember his true self between the swings of his mighty axe.

Methodology

Data window
Preview sample — a one-time snapshot of 65,406 ranked games (Master+, EUW/KR/NA, patch 26.18), counted by GamGem while our Riot production key is under review. Figures will update daily once it is approved. Counted 26–27 Sept 2026; patches 26.18 (35,477) · 26.19 (18,580) · 26.17 (11,048) · 26.16 (293) · 26.15 (8); by server EUW 22,382 · KR 21,922 · NA 21,065 · EUNE 20 · TR 17. 642 games without a result — remakes ended by vote in their first minutes, and games recorded with no winner — were not counted.
Rank aggregation
Master, Grandmaster and Challenger, pooled — the three ladders the count read its players from. Splitting further leaves samples too small to separate a real effect from noise.
Role assignment
A champion is filed under every lane that holds at least a tenth of its counted games — the position the match itself reports, not the champion’s class. Its headline win rate is across all of them; each lane’s own win rate and games are counted too, and a lane’s tier list ranks by them.
Counters
The two champions in the same position on opposite teams, over that pairing’s own counted games — ranked on the edge pulled toward zero by its sample size, printed raw.
Minimum sample
None — no figure is hidden for being thin. Every rate prints its games, and the confidence band is its 95% margin: Very High within ±1.5 points, High ±2.5, Moderate ±3.1 (1,000 games), Low wider.
Why a build is not a cause
An item is counted when the match ENDS with it, so late items show long games and an item bought when already ahead shows games that were being won. Correlation is what a rate can show; it is not evidence that buying the item caused the win.
Where the numbers come from
Names, classes, abilities, items and runes are Riot Data Dragon. Win, pick and ban rates, builds, keystones, spells and matchups are counted by GamGem from Riot's ranked match records. An estimate, not a count: this panel is not in the preview sample, and is labelled so.
